I guess that we play amidar instead amidar1. Amidar1 is probably the easiest version and it can be marathonable. Amidar is pretty close same as Amidar (Stern version), afaik. @Phil. Actually I did 5m something on amidar long time ago, but I took it off and replaced with that 2.999m replay.

Yes we play amidar, and you must use wolf166 (the actual amidar wasn't avalaible under 106).
I agree with Notman, amidar1 (1981) is the easiest version : you have 4 jumps for each level, and an extra life every 50k (30k, 80k, 130k etc infinite).
As it was marathonable, amidar (1982) came back but with 3 jumps only

And if you want to play hard version, as far as I remember, amidaro (amidar from Olympia) has only 1 jump per level
